A grip on what's inside : A clathrochelate ligand controls the oxidation state of the encapsulated cobalt ion in complex 1 . This complex can be reduced chemically in acetonitrile solution by treatment with silver in the presence of tetraalkylammonium or tetra(dimethylamido)phosphonium halides to the dark‐blue reduced complex [(NMe 2 ) 4 P]‐ 1 in high yield (see scheme).
